Amanufacturer of a consumer electronics products expects 3% of units to fail during the warranty period. a sample of 500 independent units is tracked for warranty performance. (a) what is the probability that none fail during the warranty period? (b) what is the expected number of failures during the warranty period? (c) what is the probability that more than 2 units fail during the warranty period?

a) 0.0000002, b) 15, c) 0.99996.

Step-by-step explanation:

Since we have given that

n = 500

p = 3% = 0.03

q = 1-0.03 = 0.97

So, we will use "Binomial distribution".

(a) What is the probability that none fail during the warranty period?

(b) What is the expected number of failures during the warranty period?

(c) What is the probability that more than 2 units fail during the warranty period?

Hence, a) 0.0000002, b) 15, c) 0.99996.

c.35

step-by-step explanation:

8+13=21

21+8=29

29+6=35

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
